Title:
  Hang with >1 CPU after "Restart now" button pressed

Status in ubiquity package in Ubuntu:
  Won't Fix

Bug description:
  The install system hangs after every install, after the user clicks
  the "Reboot Now" button.   The desktop disappears and "Ubuntu 17.10"
  in white typeface appears, but then nothing.  The system must be reset
  to regain control (the installed system then works).

  I'll attach a screenshot of a VM in the hung state, and also an
  archive of files left in /var/log/installer/

  STEPS TO REPRODUCE (using Virtualbox):

  1. Download the 17.10 Desktop iso image from https://www.ubuntu.com/download/desktop/thank-you?version=16.04.3&architecture=amd64
  2. In virtualbox, create a new VM with a newly-created virtual disk;
     attach the iso image to the virtual optical drive, and start the VM.
  3. Select "Install" when prompted, then take all the defaults (no download in background, no extra codecs, etc.)
  4. When finished, click the "Reboot Now" button

  RESULTS: hangs
